I think it is a very easy swap, the springs and every thing else should fit fine. Two things that could be issues; 1. the dana 60 that you get may have different size rotors, depending on the year, 2. the drag link and tie rods may be different than what you have. oh, also you may have to remove some brackets that are used for the IFS. but very simple over all. depending on how much off road/wheeling you will be doing, the king pin knuckles are stronger than the ball joints. Im not sure what years would be best,but make sure that you have the same gear ratio as the rear. This is the best upgrade that you can do for the f-250, for sure !! Also I would be sure that all seals are like new, before installing it. especially the inner oil seals, its a lot easier to replace them with the thing out. good luck !!

forget about the reverse shackle swap, its a waste of time and money. if you can find a set of Super Duty springs for free or very very cheap use them, unless stay with your stockers, alot better.

the king pin style Dana 60's were in 91 and under i think?? and ball joints came in in 91 and up. DEF get a king pin IMO. less to go wrong and the king pins dont wear out as quick as ball joints.

try to stay 80's an 90's style, and if your getting it out of a donor truck you will need the track bar mount thats on the frame, also you will need all the steering pieces as the Dana 50 ones are different.

also as said before make sure the 60 has the same gear ratio, as the gears in your dana 50 wont fit into the 60 i think??? ( not 100% sure on that one)

i've not done this mod yet, but am going to when my time will allow, i have a donor truck, and have researched this alot , also subscribe to the OBS chat and ask your questions in there.... lots of guys there that have done this swap and with all kinds of information

I agree the RSK is just not worth the hassle unless you use SD springs, I didn't have that options(SD spring) and my truck doesn't ride any better than it did stock, and was one of the BIGGEST PITA mod I've ever done to my truck. I tow a 5er and I my trailer is already nose high going down the road and any extra lift is out of the question.

The best mod for a f-250 obs is a front dana 60 swap !! I agree that the stock springs on both the f-250 and f-350 obs are not good; mine actually had negative arc, two leafs is not enough with that heavy 7.3. I have heard that the SD springs work good, but I used skyjacker 5 leaf pack with 3" lift, front and back, flipped my rear shackle brackets, installed nitro 8000 shocks; what a difference !! WOW The truck is amazing now the ride with the stock springs was hard and harsh, and now it is soft but firm. I replaced the ball joint also, and that eliminated almost all of the slop in the steering, they didn't seem like they were shot, but what a difference !!
